Like90 Rustproofing Kit: A Complete Thin-Film Corrosion System

Like90 is best known for products built around the needs of collision repair facilities, and its Rustproofing Kit is a good example of that focus. Instead of a single can of undercoating, the Like90 CIC (Corrosion Inhibiting Compounds) Kit, part number 10010, bundles everything needed to restore corrosion protection to metal that has been cut, welded or straightened during a repair.

What Is in the Kit

The kit pairs four aerosols with a dedicated application wand and storage caddy:

• CIC Weld-Thru (black): a thin-film coating designed for cleaner, stronger welds than traditional weld-thru coatings. Its non-conductive resin contains no zinc or copper, which can promote corrosion and contaminate the weld, and it performs on aluminum as well as steel.
• CIC Dry Film (clear): a super-penetrating compound that wicks into seams and crevices at about 4 inches per hour, reaching the exposed metal around a weld joint where conventional products struggle. It can be applied right after welding or later after paint.
• CIC Wet Black: a self-healing penetrating cavity wax. Like90 cites 4,000 hours of salt spray resistance on steel, compared with 1,000 hours for a leading cavity wax.
• Remover aerosol: for cleanup of overspray and unwanted residue.
• 36-inch CIC Flex Wand: includes a 360-degree spray tip for coating the inside of rocker panels, rails and other enclosed sections.
• Aluminum aerosol caddy: holds four cans and mounts to a tool cart or nearby wall for easy access at the work bay.

Why Thin-Film Technology Matters

Traditional rustproofing often relies on thick coatings that sit on the surface. Like90's thin-film approach is different: the compounds creep into tight seams and overlapping panels, which is where moisture tends to collect and corrosion begins. The formulas also avoid metals such as zinc and copper that can contribute to galvanic corrosion between dissimilar metals. Like90 describes its CICs as bringing aerospace-level corrosion protection to collision repair.

This matters more as modern vehicles mix high-strength steel with aluminum. Corrosion protection is typically required to be restored as part of the repair process, and a system tested on both metals simplifies that step.

Practical Considerations

• Compliance: the aerosols are VOC-compliant, including California's strict regulations, and are packaged in cans designed not to clog.
• Workflow: the compounds are sequenced for use before, during and after welding and paint, so one kit covers multiple repair stages.
• Best fit: the kit suits body shops, restorers and serious DIYers who repair structural panels and need protection inside closed sections.

For anyone restoring corrosion protection after welding or panel replacement, the Like90 CIC Kit offers a well-organized, application-specific system. Visit the Like90 brand page for other shop products, or the Rustproofing Kit category for more options.
